Let x=0.666.... Multiplying both the sides by 10 10×x = 10×0.666..... 10x = 6.666..... 10x = 6+ 0.666..... 10x = 6 + x 10x - x = 6 9x = 6 x = 6/9 x = 2/3

Let x=0.6666......x=0.6666...... 10x=6.666−−–––––––––––––10x=6.666−−_ −9x=−6−9x=−6 ⇒x=69=23.⇒x=69=23. Hence, the answer is 23.

Yes 0 is a rational number. We can write it in the form of p by q where p and q are integers and q is not equal to zero as 0 is integer and we can write it in form 0/1 so it's a rational number . Examples 0/5,0/7,0/9

Every integer is clearly a Rational Number. Clearly, 5/2,-4/3, 3/7, etc. are all Rational Numbers but not Integers. Therefore, every integer is a Rational Number but a Rational Number need not be an Integer.
